Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S-8261ACHMD-G4HT2U is determined by the following critical parameters:

Parametric Equivalents (ABLIC Inc. S-8261 and S-8240 Series):

• Battery Chemistry: Lithium Ion/Polymer
• Number of Cells: 1
• Fault Protection: Over Current, Short Circuit
• Package / Case: SOT-23-6
• Mounting Type: Surface Mount
• Operating Temperature: -40°C ~ 85°C (TA)
• RoHS Status: ROHS3 Compliant
• MSL: 1 (Unlimited)

Parametric equivalents differ only in packaging format (Tape & Reel vs. Cut Tape) or base product series designation (S-8261 vs. S-8240), with no impact on electrical function or thermal performance.

Similar Part (Texas Instruments BQ29703DSER):

• Battery Chemistry: Lithium Ion/Polymer
• Number of Cells: 1
• Fault Protection: Over Current, Over/Under Voltage, Short Circuit
• Operating Temperature: -40°C ~ 85°C (TA)
• RoHS Status: ROHS3 Compliant
• MSL: 1 (Unlimited)

The BQ29703DSER is classified as a similar part due to package format difference (6-WSON vs. SOT-23-6) and expanded fault protection capabilities (includes Over/Under Voltage protection). PCB layout and footprint redesign is required for this substitution.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (No PCB Redesign Required):

S-8240ACS-M6T1U, S-8240ADZ-M6T1U, S-8261AAJMD-G2JT2G, and S-8261AAJMD-G2JT2U are direct substitutes for the S-8261ACHMD-G4HT2U. All maintain identical electrical specifications, thermal operating range, fault protection capabilities, and SOT-23-6 package footprint. Selection among these parts is based on packaging format availability (Tape & Reel vs. Cut Tape) and inventory requirements. All parts are Active status and ROHS3 Compliant.

For Alternative Sourcing (PCB Redesign Required):

The BQ29703DSER from Texas Instruments is a similar part suitable for applications requiring expanded fault protection (Over/Under Voltage detection in addition to Over Current and Short Circuit). This part requires PCB layout modification due to 6-WSON package format versus SOT-23-6. Selection of this part is appropriate when design specifications mandate voltage monitoring capabilities beyond the base protection set.

Frequently Asked Questions (FAQ)

Q: Can S-8240ACS-M6T1U replace S-8261ACHMD-G4HT2U without PCB changes?

A: Yes. Both parts share identical SOT-23-6 package footprint, electrical specifications, operating temperature range, and fault protection capabilities. The substitution requires no PCB redesign. Difference exists only in base product series designation (S-8240 vs. S-8261) and packaging format (Tape & Reel).

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape (CT) packaging provides the same components on tape segments cut to specified lengths, typically for lower-volume or manual assembly applications. Electrical and functional specifications are identical.

Q: Why does BQ29703DSER require PCB redesign?

A: The BQ29703DSER uses 6-WSON (1.5x1.5) package format, which differs from the SOT-23-6 package used by the S-8261ACHMD-G4HT2U. Different package footprints require modified PCB land patterns and trace routing. Pin assignments and electrical interface may also differ, necessitating schematic review.

Q: Are all substitute parts ROHS3 Compliant?

A: Yes. All listed substitute parts maintain ROHS3 Compliance status, consistent with the primary part S-8261ACHMD-G4HT2U.

Q: What fault protection does each part provide?

A: S-8261ACHMD-G4HT2U, S-8240ACS-M6T1U, S-8240ADZ-M6T1U, S-8261AAJMD-G2JT2G, and S-8261AAJMD-G2JT2U provide Over Current and Short Circuit protection. BQ29703DSER provides Over Current, Over/Under Voltage, and Short Circuit protection.

Q: Can I use S-8261AAJMD-G2JT2G in high-volume production?

A: S-8261AAJMD-G2JT2G is supplied in Cut Tape (CT) format, which is typically used for lower-volume or manual assembly. For high-volume automated assembly, Tape & Reel (TR) format parts such as S-8261AAJMD-G2JT2U or S-8240ACS-M6T1U are recommended.
